Learn Polish: Kiedy będziemy planować następny projekt? - When will we be planning the next project?

This is the imperfective future tense, used for ongoing or repeated actions in the future. It is made by combining a future form of the verb 'to be' (być) with the infinitive (basic dictionary form) of another verb. Here, będziemy gives us the 'we will' part, and planować provides the action 'to plan'.

Is there another way to form this future tense besides using the infinitive planować?

Yes! In Polish, you can form this future tense in two ways: using będziemy + the infinitive (planować), or będziemy + a past tense form (planowali). Both are perfectly correct and mean the exact same thing. The infinitive version used in this sentence is often easier for beginners because you do not have to worry about matching the gender of the speakers!

Could I include the word for 'we' (my) in this sentence?

Yes, you could say Kiedy my będziemy planować..., but in Polish, subject pronouns are usually dropped. The 'my' ending on będziemy already clearly tells us that 'we' are the ones doing the planning, so adding the pronoun isn't necessary unless you want to add special emphasis.

Why doesn't the ending of następny projekt change, since it is the direct object of the sentence?
